Polishing device for inner wall of pressure pipeline

Abstract

The invention relates to the technical field of pipeline machining, in particular to a pressure pipeline inner wall polishing device which comprises an executing mechanism, a polishing mechanism, a polishing mechanism, a polishing mechanism and a polishing mechanism, the executing mechanism is of a regular polygon connecting rod structure formed by hinging a plurality of connecting rods, and polishing wheels are rotationally arranged at the hinged positions of the outer sides of the connecting rods; the driving mechanism is used for driving the regular polygon connecting rod structure to stretch. Spiral shafts are further rotationally arranged at the hinged positions of the outer sides of the connecting rods, and the spiral shafts and the polishing wheels are arranged at intervals. A first rotating wheel and a third rotating wheel are rotationally arranged at the outer side hinging position of the connecting rod and are arranged at an interval, and a second rotating wheel is rotationally arranged at the inner side hinging position of the connecting rod; the second rotating wheel and the first rotating wheel are in transmission through a transmission belt, and the second rotating wheel and the third rotating wheel are in transmission through a transmission belt; the spiral shaft is arranged on the first rotating wheel, and the polishing wheel is arranged on the third rotating wheel. The invention further discloses a pressure pipeline inner wall polishing method, pressure pipelines with different pipe diameters can be ground and polished, the structure is simple and compact, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pipeline processing, in particular to a device for polishing the inner wall of a pressure pipeline. Background technique [0002] Pipes have a wide range of applications in industrial engineering and daily life. In order to prolong the service life of metal pipes and avoid mechanical failures, it is necessary to grind and polish the inner wall of the pipe, especially the welding seam and rust. However, due to the special working space limitation, the grinding and polishing of the inner wall of the pipeline is difficult to be done manually, and a corresponding grinding device needs to be developed. [0003] The pipe inner wall grinding and polishing device in the prior art has a small adaptability range or even cannot adapt to different pipe diameters, and has a complex structure and large volume, which is inconvenient for operation. SUMMARY OF THE INVENTION [0004] In order to solve the technical pro...
